Different kinds of flowers grow in different kinds of habitats because that is what they have become accustomed to, through the process of evolution over millions of years. Certain geographic conditions suit only certain kinds of flowers. In the original sense, climate is a concept used to divide the world into regions sharing similar climatic parameters. But some flowers, like acacia, roses, sunflowers, etc., are found very commonly all across the globe in all kinds of climates. However, such flowers are rare. Most flowering plants are climate-specific, and can be classified on the basis of temperature and precipitation.Geographically, the globe is divided into 3 Zones:

Tropical

Temperate

Polar

Tropical Zone:This portion of the Earth lies mostly around the Equator; limited in latitude by the Tropic of Cancer in the North, and the Tropic of Capricorn in the South. These are areas where the Sun reaches directly overhead at least once every solar year. They mostly have a dry/wet season. The areas which fall in this zone are the Amazon Basin in Brazil, the Congo Basin in West Africa and Indonesia, India, southern China, southern Africa, South America, and the north coast and central Australia, southwestern United States, northern Mexico, Argentina, a major portion of Africa.Tropical Flowers: Flowers native to the tropical zone include: African Moon, African Tulip, Agave, Alpine Aster, Alpinia, Amaryllis, Amazonlily, Angel Wing Begonia,Annual Delphinium, Begonia Fairlady, Begonia Non-stop Red, Bitter Gourd, Blanket Flower,Bleeding Heart Vine, Blood Lily, Blue Alpine Daisy,Blue Dawn Flower, Blue Jacaranda, Blue Passion Flower, Bottle Brush, Butterfly Jasmine Mariposa, Calatheas, Cally Lily, Catasetum, Cattleya,Cautleya, Christmas orchid, Constantia, Cosmos Pink, Cyrtopodium, Dahlia,Day Lily Frans Hals, Decorative Dahlia, Encyclia, Etlingera, Flame of the Forest, Frangipani, Golden Shower, Grass of the Dew, Heliconia, Hibiscus, Inca Magic flower, Jasmine, Kantuta, Koutruk Lei, Laelia, Lotus, Maxillaria, Melati (Jasmine) (Jasminum sambac), Moon Orchid Phalaenopsis amabilis (also known as the anggrek bulan), Musas, Orchid, Poinciana or Flamboyant Delonix Regia, Rafflesia arnoldi (Alpine Aster Pink), Sampaguita, Sophronitella, and Sophronitis.Temperate Zone:Regions in this zone lie strictly between either he Tropic of Cancer and the Arctic Circle or the Tropic of Capricorn and the Antarctic Circle. The average temperature in these places is usually more than 50 Degrees Fahrenheit (10Degrees Celsius). Southwestern South America, New Zealand and Tasmania, northwest Europe (small pockets in Ireland, Scotland, Iceland and a somewhat larger area in Norway), southern Japan, and the eastern Black Sea-Caspian Sea region of Turkey and Georgia to northern Iran etc., come under temperate zones. The flora in these regions has adapted to the temperate climate or typically needs this climate to flourish.Temperate Flowers: Flowers that grow in a temperate climate are Maple Leaf, Rose, Pomegranate, Lotus, Iris, Centaurea or Knapweed, Sunflower, Tulip, Chrysanthemum (imperial) , Cherry Blossom (Sakura), Golden Wattle (Acacia pycnantha), Kowhai (Sophora microphylla).Polar Zone:Simply put, these areas are the areas surrounding the North Pole and the South Pole. These regions lack any trees, and may also be covered with glaciers or a permanent or semi-permanent layer of ice. The less severe polar climate is the tundra climate. Antarctica and coastal areas on the island of Greenland are the only regions on the globe with a polar climate. Tundra climate prevails across the northernmost part of the Eurasian land mass, from the northern tip of Scandinavia and eastwards to the Bering Strait, including large areas of northern Siberia. Large areas in northern Canada and northern Alaska also have a tundra climate, while an ice cap climate prevails in the most northern parts of Canada and Northern Iceland.Polar Flowers: Flowers that are native to polar regions include Maple Leaf, Linnea (Linnea Borealis), Purple Heather (Calluna vulgaris), Jasmine and Willow Herb.
